BackgroundWe have performed transanal pull-through (TAPT) for Hirschsprung disease since 1998. Some of our patients after TAPT showed a patulous anus and suffered from severe true fecal incontinence. We performed anal canal plasty for these patients and evaluated its efficacy in restoring anorectal function.MethodsThirty-one patients who were â¥Â 5 years old were previously operated on for Hirschsprung disease, and seven (22.5%) of these were indicated for this procedure. Anorectal function was evaluated using the Japanese Study Group of Anorectal Anomalies (JSGA) clinical assessment of defecation function score. For surgery, the patients were positioned in the prone jackknife posture. The posterior half of the anal canal was exposed and folded inward until the anal canal lumen was as narrow as the surgeon's index finger. External anal sphincter muscles were repaired, and the wound was closed vertically.ResultsThe mean preoperative JSGA score was 1.42 ± 0.4. The mean JSGA scores at 2-6 months and 2 years after this procedure were 5 ± 2.1 and 5.8 ± 2.1, respectively. Postoperatively, the JSGA score significantly improved at both times (p < 0.05).ConclusionsAnal canal plasty may be effective for true fecal incontinence and a patulous anus after TAPT. This surgical approach may be useful for these conditions.Level of evidenceType of study: Treatment study, Level IV.
